Finger safe
Worlds first finger safe power fuse system
Smallest footprint of any class fuse including class J, CC, T and RK
Meets class CF and class J time delay electrical performance requirements
Indicating version features easyID™ open fuse technology for faster troubleshooting and reduced downtime
Faster response to damaging faults to help reduce destructive thermal and magnetic forces
Long time delay minimizes nuisance circuit openings due to temporary overloads and transient surges
High interrupting rating to safely interrupt faults up to 300 kA
No venting of arc or molten metal and gases during opening
Robust cycling and inrush current withstand
Low let through currents under fault conditions
Provides type 2 no damage in protection for IEC motors starters when properly sized
Easy selective coordination with any other Cooper Bussmann low peak class CC, L, J and RK1 fuse with simple 2:1 amp ration between upstream and downstream fuses
-40 to 80 deg C operating temperature
300 kA RMS symmetrical (UL) and 300 kA RMS symmetrical (CSA) at 600 VAC, 100 kA (UL and CSA) at 300 VDC interrupt rating
Copper alloy terminals, electroless tin terminal plating, PES (polyethersulfone) indicator lens, energetic chemical indicator
10 sec at 500% response time
